Extended validation for CD13 Antibody, anti-human,


Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.
Other clonesOverlap in epitope recognition with REAL312
Cells were incubated with an excess of purified unconjugated CD13 (REAL312) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Specifications for CD13 Antibody, anti-human,


Clone REAL312 is an antibody fragment derived from the full CD13 antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity.
Clone REAL312 recognizes the CD13 antigen, a type II transmembrane glycoprotein, which is also known as aminopeptidase N or gp150. CD13 is expressed on granulocytes, myeloid progenitors, endothelial cells, epithelial cells, and subset of granular lymphoid cells. It is also broadly expressed in other tissues such as kidney proximal tubules, intestine, and placenta. CD13 is an enzyme that is used as a biomarker to detect damage to the kidneys. It also serves as a receptor for one strain of human coronavirus that is an important cause of upper respiratory tract infections. Defects in CD13 appear to be a cause of various types of leukemia or lymphoma.
The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes.
